NO EXCUSES! Home workout [Note to self: add 1 min plank to rotation and instead of burpees do mountain climbers and/or spiderman crawls). No excuses. Even if the day is hectic at least do this exercise at home
High Intensity Interval Training in the comfort of your home! Do the entire thing twice through, with a two-minute rest between sets, and push yourself hard during the non-marching sections. Great for dorm rooms!
